| acceleration |
The rate of change with time of the velocity vector of a particle. If u is the vector velocity, the acceleration may be written as Du/Dt, where D/Dt is the material (or total) derivative. For most purposes in hydrodynamics where Eulerian coordinates are employed, the acceleration is decomposed as follows: where u/ t is called the local acceleration, and u ?u is called the convective acceleration.

| accretion |
1. (Sometimes incorrectly called coagulation.) In cloud physics, usually the growth of an ice hydrometeor by collision with supercooled cloud drops that freeze wholly or partially upon contact. May also refer to the collection of smaller ice particles. This has been called a form of agglomeration and is analogous to coalescence, in which liquid drops collect other liquid drops. See ice accretion; compare coagulation. 2. ...
